用GSR金选择树脂矿浆工艺从金矿和含银金矿中分离回收金银的研究

Study on the Recovery of Gold and Silver from Mudy and Carbonaceous Ores with High Selectivity Resins GSR

研究了GSR金选择树脂和普通阴树脂对氰化金银矿矿浆中金和银的吸附回收率及其影响因素。结果表明,该工艺能使泥质和碳质金矿的金浸出率提高5%～66%,银浸出率提高24%～31%。金银吸附率分别达到99.1%和95.2%以上。

This paper studied the sorption coefficient for Au(I) and Ag(I) in cyanide pulp of mudy and carbonaceous ores with GSR-resins and common anion exchange resin,and its influence factors.Results showed that,for Au(I),the leaching efficiency increased by 5%～66%,which for Ag(I) increased by 24%～31%.The sorption coefficient for Au(I) was higher than 99.1%,and higher than 95.2% for Ag(I).
